Golden textile" self-developed salt-free dyeing technology

By Zou cheaponsale

A small supply use, little ecological toxic waste and salt-free dyeing technical knowledge, at a fresh township is found in Shaoxing Anchang direct textile golden Ltd. productively deduced and utilised in bulk cotton material, CVC, nylon and other fibers into woven cloth dyeing Medium. Two days in the past, golden textile financial gatherings have the technical knowledge to the National Patent Office resolved the two patents.

Golden goal is a collation of textile dyeing and printing an annual output of 80,000,000 meters of Buda company executives Jingen land attached great importance to energy saving and environmental protection. A few years ago, he and several of Donghua University in Shanghai to talk to be a Teacher information: due to the traditional dyeing process requires the use of many inorganic salts, and the application of inorganic salts there is a serious problem of environmental pollution. Therefore, there is no salt in dyeing technology research and development. However, the high cost because of the application can not be used in volume production. Lu Jin-Gen that the information immediately aware of the opportunities. Soon, he set up his own company at the salt-free dyeing technology research and development group.

Golden company's expertise R & D staff in the objective directly after the check in the lab to do. Abroad because there is no precedent for this expertise, all depend on to perform their own study to explore. R & D in alignment to change the fiber with a contradictory electric auxiliaries, mechanical employees until 2007 effectively evolved salt-free dyeing auxiliary chemicals and low-volume applications. However, they furthermore came across the difficulty of high cost of publishing and dyeing. In this consider, technical and mechanical staff in the company's powerful support of the authority, to extend research. They are low-cost chemical raw components assortment as the best synthetic additive formula; a change in the customary publishing and dyeing expertise, at the outset will be dyeing gray piece of cloth on the ambient warmth of the container, gradually through the freezing revolving mill will be one swap fabric, and then will be revolved up piece of cloth, and then put in salt-free dyeing the dyestuff vat. Numerous checks and eventually did well in apprehending the high cost of the submission of this problem.

According to introduction, for the dyestuff to be adsorbed on fiber piece of cloth, the customary dyeing piece of cloth each cylinder should be one stained Add 200 kg of saline to make fabric color. Emission of large-scale use of inorganic salts, both an boost of work power, but furthermore origin ecological pollution. Salt-free dyeing auxiliary fibers can be changed to deal with its cationic exterior, which in dyeing with reactive dyestuffs encompassing anions developed upon the culmination of staining affinity.

Golden textile company independent research and development of non-salt and salt-free dyeing auxiliary dyeing technology, high-tech, low resource consumption, less environmental pollution, good economic returns, to promote the value of highly. Last year, the company is about two-thirds of 68 million meters of dyeing fabric dyeing cotton fibers, the New Year to more than 530 tons of salt, reuse, and 20,000 cubic meters of water-saving, and fixing the rate of dye greatly improve, dyeing fiber handle well, colorful.

The company's salt-free dyeing of fabric issuing and dyeing technical knowledge of recent textile development by the provincial Institute of Textile Testing Center of detection, the polishing fastness, bathing fastness, shade of color fastness to perspiration-resistant are in line with countrywide standards. Enterprise is in the method will be stated to the technical knowledge, bring ahead a countrywide systematic and technological improvement rewards and countrywide high-tech enterprises. - 18299
